I have wondred about the rolling stock for crossrail services but one
question i have is that couldn't some 2/3 carriage EMU'S be built so
that peak hour trains can be split/attached so that they can serve
some of the thames valley branches instead of having a shuttle on
those lines?

One such route i am thinking about is the Maidenhead to Marlow branch,
doesnt this have through services to London during peak hours?

Marlow and Henley won't be electrified as part of Crossrail (and probably
not as part of the GWML electrification). So they'll either lose their peak
trains through to/from Paddington, or these will be dmus. One reason for
running Crossrail with 10-car trains throughout the day is that the central
area stations will be double ended, so trains that use the full length of
the platforms will be desirable.

Hymek + coaches)
